A Survey on Software-Defined Networks (SDN) Firewall

Abstract

The exposure to Software-Defined Networking (SDN) paradigm is the only incentive for the concept of programmable networks that has presently retaken substantial momentum. For future Internet, SDN is one of the general rising solutions. SDN is defined by its two prominent characteristics, including the data plane and control plane decoupling and giving network application development programmability. The result of which, SDN is located to offer better performance, more proficient configuration, and higher flexibility to assist inventive network designs. Network security is the main challenge in SDN. This survey gives the overview of different SDN firewalls reflected in various research papers, and many techniques for improving SDN security through firewalls. In this survey, we analyze various research paper on network security through the firewall, deliberate their technologies, taken their comparisons and come out with best techniques presented.
